The purpose of this paper is to clarify the meaning of "Charcoal-Construction" presented by Horiguchi Sutemi in his architectural thought through analyzing his treatise titled "Charcoal of Sen Rikyu". The paper consists of three chapters : Chapter 1 suggests that Horiguchi found "complete unification of function and expression" in "Charcoal-Construction" and he made it as a basis for understanding tea ceremony. Chapter 2 tries to explicate the meaning of "Charcoal-Construction" in comparison with "the flower", where "contemplation" to appreciate "the flower" is required. Chapter 3 argues that "asymmetrical" structures in "Charcoal-Construction" make it possible for us to see it like "the flower".
